Lexus SC430 :: Random Knock On Front End When Going 5 To 10 Mph And Turning Steering To Left Or Right
Jul 9, 2013
I have just noticed a random knock on front end on 2002 430 sc when going 5 to 10 mph and turning steering wheel to left or right...sounds like metal to metal and shifting or movement knock ... turning left, sound on passenger side; turning right, sound on drivers side..brake system checked out ok; had struts, plates and insulators changed; checks were made on torques to all front suspension bolts and everything is tight and no movements in bushings and etc.. totally baffled and really an annoying sound......ball joints are tight and no movement.

My friend with an 07 with about 109k miles on it now has started getting a "groaning" noise whenever the wheel is cut hard to the right or left, either sitting still or rolling. A local repair shop (not the dealer) checked it out and said there was some "stuff that needed to be lubricated". Not trusting this opinion he went to a Toyota dealer where he was getting new brake pads installed on all 4 corners (no Lexus dealer in the city where he lives), they diagnosed the car as needing 4 new struts and a new balljoint.
If in fact he does need the struts and balljoint, I am thinking chances are there will be a bunch more suspension stuff that should really be done at the same time when everything is apart anyway - perhaps bushings, endlinks, etc?
Is he better off sticking with the OEM strut replacements or should he go aftermarket? He's not looking to slam the car or anything, and is more of a ride comfort guy than handling enthusiast.

I have had my struts replaced at local gas station. Unfortunately, there is now an occasional hard steel on steel knock in the front. Very weird indeed.
Is there something they may have missed when they installed them?

I have a 2013 es 300h.
To make a long story short, i had to have my front bumper replaced in May due to an accident but there was no mechanical damage to the car. They did an alignment to the car just to be safe.
Earlier this week, I'm not sure why I noticed that the steering was a little tight/heavy when turning left or right sometimes. It wasn't a major challenge just a little more strength then when driving straight.
Today, I took the car to the dealer and they ran all of the tests and everything came up fine except there was a code that the hybrid battery had been disconnected during the repair while sitting at the shop which created some sort of code that they cleared. The tech mentioned that this may have created the steering issues since the car may have thought their was low power.
After, I did notice it was a little better but still a little tight at times. I took the car back to the dealer and had the tech drive the car and he said the steering was normal for the car. Are they missing something or is it that I forgot how the car drives?

Just replaced inner and outer boots. All seemed to go well. Just got done with some errand and noticed a light knock on the driver side when turning left. What might cause this?

First: 2007 GX470 with 63k miles
On some 'cold' starts (and I use that term very loosely, because it never really drops below 40 degrees here), when the engine has sat overnight, and when I shift into reverse (never Drive, just Reverse) and stand on the brake I get a knock. I don't hear it in Park. Not valve clatter like on my german cars while the oil gets routed to the lifters, but instead a loud, startling deep-down knock that sounds like BAMBAMBAMBAMBAM. Then it goes away. Put it in neutral and the revs rise and it's gone. Put it in Drive and nothing there. Just lasts for maybe 5-10 seconds, but is it loud. BAMBAMBAMBAM! Like someone hitting a 2x4 on the block or tranny housing.
Once I'm past that 5-10 seconds it won't do it again all day. Just after a "cold soak". And perhaps 5-10% of the time.
There is a lot of examples with this motor of what some call "piston slap". Don't know if I have it - and I suppose it might get worse (to the point where I hear it) when the engine is cold and under load (in gear), but I don't get it in Drive. Just Reverse.

I posted in this thread originally: [URL] .....
But today I had my wife drive the car and take some slow left turns while I listened so I could get a better idea about what the sound was and where it was coming from. From inside the garage and in the car, it sounded like it was coming from the rear but I now know it's coming from the front passenger wheel and it is not a "grinding" sound at all, it's more of a tick-tick-tick/click-click-click sound.
Applying brakes doesn't change the frequency or quality of the sound, but speed does. The faster the wheel turns, the frequencly of the ticking increases. It doesn't appear to tick/click only once per revolution, it clicks a number of times throughout the rotation and at some points during the rotation it clicks more often than others. Like, tick.... tick... tickticktick...tick...
When going straight there is no noise, turning right, it sometimes might click once or something but it doesn't really happen turning the other way. I've looked at the dust shield around and even tried bending it back a little bit in case it was making contact when I thought it was more of a grind but nothing looks out of place and nothing has been done to the wheel recently other than putting new rims on a couple of months ago.
Wheel bearing? I thought a bad wheel bearing would make noise no matter what direction you're going and pretty much constantly. CV? I thought CV ticking usually only happens at full lock but it ticks even on not so severe turning. Fender liner doesn't appear to be touching the tire, and the car isn't dropped and is AWD so there's plenty of clearance.
So, is this a trip to the dealer? I'm only under powertrain... not sure if something is up if it would be covered. I think wheel bearings are, but not sure about other suspension parts that might cause this.

I noticed my engine light and vsc lights came on two days ago and then after a restart went away.
It's been two days and today the lights came on again and I noticed a hesitation in acceleration.. got the codes scanned I believe they were p0330 and p0325 for bank 1 sensor 1 knock sensor. They wiped the code so I'm going to drive it to see if it comes back on? Where is this sensor located?

My left side mirror, motor will move left and right but it will not move up and down. Is there a DIY way to fix this? Is it a motor problem? Can I buy the part and fix it?

2010 F-150 King Ranch. Randomly when turning left, it feels like the left front brake is engaging and it sounds like your anti-lock brakes when you come to a stop on slush or snow. The truck slows with your foot still on the gas, Saturday it came to a complete stop before it released.
I have had it to 2 Ford dealerships, the first could not get the symptom to occur on a test drive and told me there was nothing they could do because they did not now what to look at.
The dealer I bought it from got it to act up, replaced the IWE 2 weeks ago and 3 days later was still doing same thing. My wife dropped the truck at the dealer again Weds.morning, she told them it did it on the way there. I called at 4:30 to check and they said they drove it 2 times and it did not act up.

Over the last few months I was having a problem with my 2002 SC430 with 130,000 miles having random hiccups and engine hitches during acceleration and even at random times while on the highway or around town. My average 10 minute trip around town would have at least 10 hiccups, all random and during no specific style of driving. No one wants a stuttering engine!
After reading some of the threads here there were several options...
1. Do a system reset by using only the key turned on and pressing on the gas pedal for thirty seconds. While optimistic, this didn't solve the problem...
2. Many threads suggested that it may be my TPS (throttle position sensor) so I started shopping around for a sensor to install myself. They run for about $75 online and are a pretty easy install..but I wanted an official opinion so I went into my local lexus dealership to ask them if this was the best course of action...
The solution: Apparently, the 430 engine is a notorious carbon producing engine so, as my local lexus mechanic explained, this carbon can build up in the throttle body, affecting how the mass air flow sensor (MAFS) is read. My mechanic recommended having a FUEL INJECTION SERVICE. This service cleans the fuel deposits in fuel injectors and carbon build-up in cylinder heads and in the throttle body plating.

I have an issue with my new 2011 F150 FX4 super crew with 5.0. I put a Rough Country level kit on the front struts which raised it 2.5 inches and looks great. The issue is that there is a low speed knock heard on the left side and felt through to the steering wheel. The truck has been aligned to factory specs. all bolts have been tightened, the strut has been taken off to check the top mounting bolts. Nothing appears to loose. Can't find anything. Am I forgetting something. Rough Country said it can't be the kit. It has bee used for sometime with no issues.

I own a 2004 VW GTI VR6, with 70k miles. i bought it used (at 40k) from carmax. Ever since I've owned it I have had a problem with a single loud knock sound i can hear from my front left wheel.
it happens in two scenarios1) when i back out of a parking space and start turning my wheel - it's only a single knock (hence i don't think it's the CV, and its been pretty constant for at least 2 years), and happens at about halfway through the steering wheel travel.2) it also happens when i accelerate hard, or decelerate. it's a single knock, or pop, or clunking sound. it almost feels like something is loose, or reseating itself as the car puts pressure on the wheel as i accelerate, and then again once again when the car decelerates.
it's pretty damn loud, and disconcerting... i can feel it in the steering wheel as well. it seems to be louder when the car has not been driven for a few days.
I've taken the car back to carmax several times over the past three years but they have not been able to find the fault. they have replaced my engine mounts twice (in 30k miles that I've had the car), which i also think is a little weird. they have also replaced all the tie rod ends, etc. - all the obvious stuff.
I am at my wit's end here - carmax pretty much think I'm crazy, and my warranty has run out, but i think I've bought a car that was in an accident - i'm expecting my front end to fall apart one day as I'm driving...

When backing out of same parking spot, I always hear a clunk, clunk, clunk, noise in the front while turning the steering while back in the fixed position. I have heard this noise in the past but did not think any thing of it.
It's hard reproduce this noise, it seems to only be happening when backing out and turning the steering wheel. Car only has a little over one thousand miles.

I own a 2002 SC430 with 20,200 miles on it which I purchased new. The other day the check engine light came on. I checked it with the code reader and got the following 2 codes. P0300 (random multiple misfired detected) and C1201 (engine control system malfunction). The car ran great before, now running real ruff and when you drive it has less power.

There's been a recent annoyance that's appeared in my '03 SC 430 with 32K miles. I've noticed over the last 3 months that whenever I have the A/C turned on, after a few minutes, a soft chirping sound appears. It sounds very much like a cricket chirp to be exact, kind of high pitched, but continuous. It's even loud enough to hear over my music.
I realized that it came from the A/C because it was gone whenever I turned the A/C off. I initially thought it might be from the belts for the A/C compressor, but I couldn't hear anything from the under the hood with the A/C turned on. I'm thinking it might be something to do with how the coolant flows in the lines, but can't be sure.
I'll probably have it looked at during my next oil change.

So I was driving today with the fuel light on, drove for 5 miles and the car started dying. I was under the impression there would be atleast 2 gallons left. How many miles we have left when the light turns on?

I have a 01 Chrysler Sebring 4D Sedan. I have been working on cars many years, never done tie rods. This my first attempt, I messed something up I believe. I replaced both inner tie rods and outer ends. I followed what I thought was correct procedure., counted turns on ends coming off. Installed new ones the same amount of turns. Before I did this the steering was fine. Now when I turn sharp to the right or left, like turning in to a driveway, I get an awful binding grinding noise, and I can feel it shimmy in the wheel. It will even stop the car going hard right. I can see evidence of rubbing on the CV boot closest to the wheel on the pass side. I assume I messed up somewhere with setting the steering when I installed the Tie rod ends to the wheel hubs.

I have a noise with my new (2.6k miles) 2000 Diesel F250 Crew Cab. When I make low speed, right turns while crossing any type of depression in the road I hear a loud knock as if the left shock is bottoming out. There's an intersection near my house with runoff depressions across the road, I almost always hear the noise when making that turn. I've occasionally heard it coming from the right side when making a left turn.
